Deckarium

Deckarium is a deck-building pet simulator. Play pet cards to add to your terrarium or aquarium, and progress through levels to unlock new cards to add to your deck. Keep your pets well fed and they'll produce coins for you. Some pets have bigger appetites than others! You will have to maintain the food-chain if you want to benefit from larger pets. Your pets aren't the only ones who are hungry! Beware of ghosts who seek only to consume the souls of your pets! Beat levels and minigames to earn extra currency for your own personal idle terrarium and aquarium, where you can collect and name your own unique pets without fear of phantoms!
